ICAES provides the freedom to site zero-emissions storage where it's needed—not where geology mandates.
Existing grid-scale energy storage is dominated by pumped hydro and, to a lesser extent, classical CAES. Geology, not economics or value, mandates where these two technologies can be sited. With its patented isothermal process, SustainX’s ICAES maintains the low cost and long lifetime benefits of classical CAES and enables the possibility of siting emissions free capacity anywhere within the electricity market value chain.
ICAES’s efficient isothermal gas expansion does not require the burning of natural gas, resulting in zero emissions and independence from fossil fuels.
